Yan Chunhui, president of Yaweilang Optoelectronics, analyzed the bottleneck that the upstream can break through. He reviewed the history of the development of nitride LED technology. With the improvement of LM/W, LED applications continue to upgrade and the market continues to expand. The goal of the upstream breakthrough is high luminous efficiency (lm/W) + low cost (lm/$) + high color rendering + high reliability. The prior art is based on increasing lm/W to increase the space of lm/¥+Lm/W, which is close to saturation. For the lighting market, more than 200lm / ¥, lm / W technology is difficult to match.
Finally, Yan Chunhui proposed the direction of the extension of the square lumens: IEQ improvement, material defects fell into the key; Droop decline, LED structure design, chip heat dissipation is the key; LEE upgrade, LED structure light absorption must be minimized. At the same time, Yan Chunhui also announced the production of near-ultraviolet LED chips by Yaweilang. The internal quantum efficiency has exceeded that of blue LEDs, and the external quantum efficiency is over 50%.
Information technology has penetrated into all areas of our lives. With the progress of technology, the iteration rate of laptops is getting faster and faster. Previous laptops mainly used E-SATA, FireWire, VGA, DisplayPort, SD card slot, USB A, 3.5mm headphone jack, HDMI or RJ45 ports.But manufacturers began stripping connectors from laptops to make them thinner and lighter. Most new laptops now have a USBC port (Thunderbolt or full-featured USBC) and an audio jack. The laptop is thin, but the missing ports are useless. This is where the USB C Hubs comes in.
Type C Usb Hub can support USB, PD, DisplayPort, Thunderbolt, and other protocols. Using USB HUBS, you can extend multiple common connectors directly to your laptop. Mosses are compact, so you can take them anywhere. All peripheral devices are centrally connected to the hub, which reduces the hassle of plugging in and out of the laptop port and makes your desktop cleaner. Let's take a closer look at its capabilities so you can determine how many ports you need.
So these are all important ports on the hub, with the exception of the 3.5mm audio jack. Also, while aesthetics are not important, choosing a nice hub will make you happier. There are rectangular, square, and circular centers on the market to meet your desk setup needs. Usually, the rectangular type is best for your desk because the cables can be well organized if all the ports are on one side of the center.
